This utilizes dendritic cells to activate a cytotoxic response towards an antigen.

Only the cells that are in both lines make both halves, which self-assemble by leucine zipper into GAL4 and activate the reporter gene.

Mature dendritic cells activate T helper cells and cytotoxic T cells.

To protect from these undesirable processes, a cell can activate the unfolded protein response (UPR) pathway.

Nitrofurantoin exerts greater effects on bacterial cells than mammalian cells because bacterial cells activate the drug more rapidly.

Similarly, diploid cells activate diploid-specific genes and repress haploid-specific genes.

Cerus uses a different chemical for red blood cells because light cannot penetrate these cells to activate a psoralen.

Cells called antigen-presenting cells bring foreign substances to the attention of specific T-cells and activate them.

Other cells of the immune system, T-cells, normally activate the body's defenses upon being signaled by macrophages that have engulfed invading viruses or bacteria.

The cells can stop actively growing and dividing (a decrease in cell viability), or the cells can activate a genetic program of controlled cell death (apoptosis).
